nsvlcs FOR' 'F EEDlNG SHEETS OF PAPER.-

S PECQIFIGA'IJIQN forming part of Letters Patent No. 592 609, dated October 2-6, 1897.

Application filed August 1 1 95- To ctZZ whom it may concern).- Be it known that I, CHARLE'sIHENRY -HE'W WOOD, a citizen of the United States of America, residing in Milwaukee, in'the county ofsuch feeding is desired, and has for its object the stopping and retaining of the same-at perfect rest at diifer'ent stationsas they pass through the machine, thesheets remaining stationary while the carrying mechanism continues in motion, thus increasing the'capacity of the mac ine,-while avoiding the tendency of displacement" at the stations and clogging of the machine. 4 My invention consists in the general construction and arrangement whereby the objects of my invention are attained. a

like letters and figures of reference indicate like parts, Figure lis a plan view of a machine embodying my invention. Fig. 2 is a side elevation in sectionon line a: a: of Fig. 1, and Fig. 3 is an enlarged section of,the middle portion of the machine'on line y yof Fig. 1.

In detail, A indicates the table of the machine; B, the table-supporting frame; 0, the driving-shaft; -D, a shaft parallel therewith, used for givingmotion to the upper tapes; E,

- a vertical shaft for the purpose of transmitto the stopping of the blank in its passage on tapes or helts,'I have notillustrated the feed- I of the upper tapes, and have shown means for cline 24 leading from 1t. In the accompanying'drawings, in which Serial no. 559,379. (in model.)

ing' or taking-off appliances. The drawings therefore do not show a complete machine, except so far as the invention seems to require.

I have shown two upper tapes and one lower of which there are two, one beneath each moving these tapes. Theupper tapes pass .run under roll 21, over roll 22, and down under roll 23, in the direction ,indicated bythe,

arrow shown inFig. 3. The lower tapes enter 5' a at the front of the machine, as shown, and, coming in contactfwith the upper tapes, pass therewith along under roll 21,there separating from the upper tapesand passing. over roll 26, beneath roll 23, in contact with the upper tapes 'agaim Roll 26' is arranged with its periphery at the highest'point slightly above I the under side of rolls 21 and 23, for the reason Extending' through frames L and iska shaft 6, .on which shaft are two stop-gages 5 5. 7 These gages reach forward and terminate in two ends, against which the blank or sheet abuts when it reaches the station J.

On the end of shaft 6 is the radial arm 7, car- I raring roll .8. The stop-gages 5 5 are raised and lowered through the operation of the parts mentioned by. cam 9, fastened on the shaft-F. Through frames L and M also extendsshaft 13. this shaft are two gages 12 12. a of shaft 13' is a radial arm 14, carrying roll 15, operated from cam 16 on shaft F. Rolls ti-vec'aifis'h'y spring 'I0,fastened' to the radar upper tapes combined with'low'er rolls, or the same form only using single tapes.

Itherefore do not limit myself strictly to'the' con- Extending downward f o On the end 90' struction shown, as the spirit of the -inventign applies to any of theseforms.

.The operation of stopping a sheet while passing through the tapes or belts is as follows: At a time when a blank fed from station 1 is ready to pass beneath roll 21 the gages 12 12 are in the position shown in dotted lines, and

marked 17, and the stop-gages 5 5 lowered, as

shown in Fig. 2'. A sheet passing under roll 21- at this moment is carried up the incline 24 onto the raised portion of table A and against the stops 5 5 by the action of the tapes or belts.

As the sheet passes beneath the gages 12 1% these gages swing down toa vertical position,

asshown in Fig. 1, also shown ill-Fig. 2 in full lines, and adjust the blank against the pushing the blank into contact'with the tapes or belts under roll 23, whereby the blank isdrawn from the position J and carried on to position K or any other desired part of the.

- machine.

Having therefore described my invention what I claim, and desire to secure by Letters Paten t, is

1. The combination with two or more pairs of upper and lower moving tapes or belts be- .tWeen which paper is carried, of a midway station on which a sheet of paper may stop duringits; passage and remaln for a limited period out of contact with the tapes or belts.

2. The combination with upper and lower moving and alining tapes or belts arranged to carry sheets of paper, of a raised platform or station located between the entrance and exit of the tapes or belts and on which the sheet is moved and raised out of contact with the lower tapes or belts during its passage onto the platform.

3. The combination with one or more movstarting a sheet of paper during its progress through the machine, stop-gages and adjusting-gages which move the paper into contact with the stop-gages after which the stop-gages are removed from the path of thesheet and the adjusting-gages push the sheet forward into contact with the tapes, substantially as shown.

4. The combination with one or more moving tapes or belts, means for stopping and starting a sheet of paper during its passage through the tapes or belts, on a stop-station around which the tapes orbelts are guided out of contact with the sheet lying on the said station, substantially as shown.

5. .The combination of u pperand lower alining tapes, a raised station to receive the sheet, intermediate of the alining end sections of the tapes, guide-rolls to carry'the upper line of tapes over and above the raised station, and means to stop and start the sheet at the station.

6. The combination of a raised platform or station, a pair of lower tapes to travel over the said station adjacent to the ends thereof, a pair of upper tapes moving in alinement. with the lower set, rolls to hold and carry the upper tapes free from the station and lower tapes, and oppositely-disposed rolls adjacent to the station to depress the upper tapes.

7. The combination of two pairs of upper and lower moving tapes between which a sheet of paper may be carried, and a stationary raised frame or station located between the two pairs of tapes and whereon a sheet of paper may stop during its passage over the station and remain out of contact with the tapes, substantially as specified.
